Title: Three layer carbon based electrode

Abstract

An electrochemical cell is described suitable for electrochemically reacting a gas with a liquid, the cell comprising at least two electrodes, wherein at least one of the electrodes is a laminated electrode having: (a) an electrically conductive first layer having a plurality of interconnecting passageways of an average diameter of from about 0.1 to about 1.0 microns, the first layer containing from about 2 to about 10 weight percent of a catalyst active for the reduction of oxygen, and having a hydrophobic carbon containing from about 80 to about 95 weight percent carbon and from about 5 to about 20 weight percent of a first hydrophobic material, (b) an electrically conductive second layer in fluid flow communication with the first layer and having a plurality of interconnecting passageways of an average diameter of from about 0.2 to about 10 microns, the second layer physically contacting the first layer and containing from about 2 to about 10 weight percent of a catalyst active for the oxygen reduction, and having a hydrophobic carbon containing from about 60 to 85 weight percent carbon and from about 15 to about 40 weight percent of a second hydrophobic material provided the second layer is moremore » hydrophobic than the first layer; (c) a substantially completely electrically nonconductive, catalytically inactive third layer in physical contact and in fluid flow communication with the second layer, the third layer being substantially completely composed of a third hydrophobic material and having a plurality of interconnecting passageways of an average diameter of from about 2 to about 20 microns; and (d) an electrically conductive current collector in physical and electrical contact with the first layer.« less
